A bacteriostatic is a compound which has the effect of preventing bacterial growth. These agents do not kill bacteria like bactericidal compounds; instead, they limit further replication of bacteria at the site where they are introduced. Several antibiotic drugs are bacteriostatic agents, with tetracyclines being a notable example.
Bacteriostatic water is used for diluting or dissolving pharmacological preparations meant for intramuscular, subcutaneous, or intravenous injection. Bacteriostatic water for injection is only for parenteral use and must be combined with pharmaceuticals that require dilution or dissolving prior to administration. Multi-dose vials enable multiple withdrawals for use with numerous preparations.
